Beschreibung:
This volume develops the techniques of perturbative QCD in great pedagogical detail starting with field theory. Aside from extensive treatments of the renormalization group technique, the operator product expansion formalism and their applications to short-distance reactions, this book provides a comprehensive introduction to gauge theories. Examples and exercises are provided to amplify the discussions on important topics.
Elements of quantum chromodynamics; guage principle, quantization, Feynman rules, regularization, renormalization group equations, solution of the renormalization group equation, asymptotic freedom, anomalous dimensions, operator product expansion, operator products, operator-product expansion in perturbation theory, coefficient functions, physical applications, total cros section for e+e annihilations, deep inelastic lepton-hadron divergences; one-loop example, proof of the soft-photon cancellation in QED, general arguments for infrared cancellation.
